STP--If you'd find stuff like that alarming or incredulous I personally hope you aren't either a pilot or a pirate; to me it shows a lack of SA and facing the reality of the situation (which is important to pirates and pilots alike). Apparently the guy had done it for months.
Not much of a threat; the airplanes got to where they were going just fine. Just a guy who (illegally) wanted to get through the hoops unencumbered (showing a lack of SA on HIS part as well). The only threat he seems to have presented so far is in suing companies for stuff they might have done wrong. Not saying one should do illegal things, but most of us found our way through high school with good looking fake ID's which worked well in much the same manner. Just a limit of the system which we don't make better by pretending it doesn't exist like mindless drones. If one can't exercise judgment and see the big picture, one should not be in the business of security, policing, OR piloting (or even pirating for that matter).
Meanwhile Aunt Betty and Uncle Fred from Iowa get strip searched while Al-Unsafe seems to get through with ease.
The point is losing the big picture on security by putting in place silly feel good measures (which only punish rank amateurs and the good guys) hurts everyone. Including apparently the crew and pax (as well as the company picking up the tab) on THIS particular flight.
